Flat Roof Systems

From small residential projects to large commercial installations. Seam Roofing delivers professional flat roofing systems that stand the test of time. We have the expertise and equipment to handle any flat roofing challenge.

Torch-On (Modified Bitumen)

Torch-on roofing utilizes multiple layers of modified bitumen membrane that are heat-fused together to create a robust, waterproof barrier. This system is specifically engineered to withstand the freeze-thaw cycles and temperature extremes characteristic of Canadian weather patterns.

Multi-Layer Protection

Base sheet, interply sheets, and cap sheet heat-bonded for redundant waterproofing and superior leak protection.

Excellent for Canadian Climates

Flexibility allows expansion and contraction without cracking, maintaining waterproofing through harsh winters and hot summers.

Self-Healing Properties

Bitumen flows and seals around minor punctures or penetrations when sun-warmed, providing ongoing protection.

10-20 Year System Life

Proper installation and minimal maintenance deliver reliable performance for one to two decades.

TPO (Thermoplastic Polyolefin)

TPO roofing is a single-ply membrane system that combines durability with energy efficiency through its reflective white surface. The seams are heat-welded to create watertight bonds that are stronger than the membrane itself, making it ideal for commercial applications.

Energy-Efficient Membranes

Reflective surface reduces heat absorption and cooling costs.

Superior Waterproofing

Heat-welded seams create bonds stronger than the membrane itself.

Chemical and UV resistant

Resists oils, chemicals, and UV degradation without becoming brittle.

20-30+ Year System Life

Delivers maintenance-free performance for two to three decades.

Tremco Roofing Systems

Tremco represents the premium tier of commercial roofing solutions, offering engineered systems backed by one of the industry's most respected manufacturers. These systems come with comprehensive warranty programs that cover both materials and workmanship, providing maximum protection for commercial property investments.

Premium Commercial Solutions

Advanced fluid-applied membranes, high-performance single-ply systems, and specialty coatings for demanding commercial applications.

Comprehensive Warranty

Industry-leading warranties with total system coverage for materials and installation.

Maximum Performance

Rigorously tested to meet or exceed standards for wind uplift, fire resistance, and weathering.

20-30+ Year System Life

Designed for extended service, with many installations lasting three decades or more.

1

Assessment

We begin with a comprehensive inspection of your existing roof structure, examining substrate conditions, drainage patterns, structural integrity, and any areas of concern. Our experienced technicians identify potential issues and document the current state to ensure we design a solution that addresses all underlying problems and sets the foundation for a long-lasting roof system.

2

Design

Based on our assessment findings, we engineer a custom flat roofing solution tailored specifically to your building's requirements, climate conditions, and budget parameters. We'll walk you through material options, insulation upgrades, drainage improvements, and warranty packages, ensuring you understand exactly what system will work best for your property and why.

3

Preparation

Before installation begins, we carefully plan substrate repairs, drainage slope adjustments, and flashing details to ensure optimal performance. Our team coordinates material delivery, schedules inspections, and prepares the work site to minimize disruption to your operations. Proper preparation is critical—it's the difference between a roof that performs for decades and one that develops problems within years.

4

Installation

Our highly trained, certified flat roofing crews arrive on schedule with commercial-grade equipment and premium materials to execute your project with precision. We maintain clean, safe work sites and communicate daily progress updates. Most small residential projects are completed in 3-5 days, while larger commercial installations typically take up to 2 weeks, depending on size, complexity, and weather conditions.

5

Quality Control

Before we consider the job complete, we conduct a rigorous multi-point inspection that examines every seam, penetration, flashing detail, and drainage point to ensure your new roof meets our exacting standards and manufacturer specifications. We'll walk you through the finished installation, explain maintenance recommendations, register your warranty, and provide you with complete documentation for your records.

Thank you so much for installing my steel roof. It looks amazing. These men were professional, and hard-working individuals. Their price was reasonable and fair. I highly recommend this company to install your roof. Within two days, my roof was completed, and everything was clean and solid.

Vlad and his team of very knowledgeable roofers have done to great jobs for me- both metal roofs, look amazing and most importantly do not leak!
They work like a symphony- everyone knows their job and does it perfectly. Terry the coordinator makes sure everything runs smoothly and is an excellent liaison for Vlad who looks after the physical roofing! What a team and a pleasure to work with! You do not find that kind of service anywhere with anything today!

Our condo board got three quotes for our flat roof replacement, and Seam Roofing wasn't the cheapest but their detailed proposal and transparent approach won us over. They identified drainage issues the other companies missed and fixed them as part of the project. Two years later, zero issues. Their labor warranty and responsiveness to our questions made the decision easy. Highly professional from start to finish.

We wanted a standing seam metal roof for our custom home in Oakville, and Seam Roofing delivered beyond our expectations. The attention to detail was remarkable. Custom trim work, perfectly aligned seams, and meticulous work. Our architect was impressed, and we have peace of mind with the lifetime material warranty. If you want quality work, these are your people!!
